Choosing a smart cleaning product is really two different decisions. Three of these products are heavy-duty liquid degreasers for grease, grime, and residue. The fourth is a window-cleaning robot for glass surfaces. You would not use the robot to scrub an engine, and you would not use degreaser on a pane you can't reach. So the first question is not which product is better; it's which job you are actually solving.
Quick take
If your mess is in the garage, on tools, engines, or shop surfaces, the degreaser group is the relevant set. If your mess is on windows and other glass, the Window Cleaner Robot is aimed at that job. The three degreasers differ in price, container count, and detail, but they all handle the same heavy-cleaning task.
Start by naming the worst mess in your routine. If it is oil-stained concrete, caked-on engine grease, or grimy tools, you need a liquid degreaser. If it is a bank of windows or a glass door that you can't easily reach, the robot is the candidate. The prices also make the split clear: the three degreasers are closer to one another in price, while the robot sits at the top of the range.

Decision matrix
The three degreaser options cover the same broad use case: breaking down grease, residue, and scum in home, factory, auto body shop, farm, and vehicle settings. They differ mostly in price, container count, and how much feature detail is attached. The robot flips the task: it uses suction and a wipe approach for glass instead of a liquid cleaner for grease. If you want a no-hands method for windows and can spend more, the robot is the route. If you need a liquid cleaner for grease, any of the three degreasers fits; the standalone option gives the lowest listed price in the group.
Product notes
#### Purple Power Cleaner Degreaser (single listing)
This is the lowest listed price in the degreaser group. The title and description point to an industrial-strength cleaner and degreaser for heavy messes, with the description mentioning home use, factory settings, auto body shops, farms, and vehicles. If you need one container to start tackling grease, this is a straightforward choice. The trade-off is that the descriptive detail is slimmer than the higher-priced degreaser option, so you won't get the same depth of specialized feature callouts. It's best treated as a simple, heavy-duty cover for general grime.
#### Purple Power Degreaser 2-Pack
This version gives you two containers in one purchase. The title describes a 5-gallon cleaner degreaser sold as a 2-pack, and the description repeats the same versatility pitch for home, factory, auto body shop, farm, and vehicle cleaning. If you expect to go through more than one jug of degreaser, this covers that demand. The limitation is that the listed price is higher than the standalone degreaser, so it only makes sense if you are ready for that much product. For a one-time garage job, the larger order may be more than you need.
#### Purple Power Industrial Strength Cleaner and Degreaser
This is the degreaser with the most detailed feature set among the three. Attributes mention concentrated, industrial strength, non-flammable, non-abrasive liquid, and the description points to automotive, garage, tools, engines, industrial equipment, and household surfaces. Choose it when those details matter to you or when you want a cleaner described for both home and shop use. The limitation is the listed price: it's the highest of the three degreaser options. The extra detail doesn't change the core action of breaking down grease and grime, so the choice comes down to whether the added feature language matters for your situation.
#### Window Cleaner Robot
This is the highest listed price in the comparison and the only product built for glass. The description highlights strong suction in the 2800-3200Pa range, remote control, four-way dual spray, microfiber cloths, and ultrasonic nozzles that spray fine water droplets. Choose it when you want a hands-free tool for windows and other glass surfaces. The limitation is scope: it won't address grease, engines, tools, or shop messes, so it's a companion to a degreaser rather than a replacement. Its price also sits above all three degreaser options.
Bottom line by use case
Start with the standalone Purple Power Cleaner Degreaser for garage grease, tools, and engines. Choose the Purple Power Industrial Strength Cleaner and Degreaser when you want the extra feature detail around industrial-strength, non-flammable, non-abrasive cleaning. Buy the multi-container Purple Power Degreaser version when you're stocking up for heavy use. And pick the Window Cleaner Robot when the surface is glass and you want a remote-control, suction-assisted clean.
